Description

[Detailed explanation of the invention] This invention is designed to lift the device that suspends the rescue bag after dropping it outside the building as stipulated in the Fire Service Act Enforcement Regulations, and in particular, lifts the link mechanism connecting the rescue bag from the mounting base and deploys it. The present invention relates to a suspension holding device for a rescue bag, which is equipped with a lifting mechanism suitable for setting to a starting state.

The applicant of this invention proposed a rescue bag storing and dropping device that automatically drops and suspends the rescue bag outside the building in order to safely evacuate the building in an emergency, especially when a fire occurs.
I suggested it earlier.

This storing and dropping device is installed near windows, balconies, rooftops, etc. of buildings. By simply pressing a push button switch installed at the installation location or halfway up the floor, the rescue bag is automatically dropped and suspended, and evacuees wait for several tens of seconds. It is designed so that a person can evacuate to a safe place by simply boarding a rescue bag from a floor or intermediate floor where a storage and dropping device is installed.

However, since this storing and dropping device automatically drops the rescue bag, the structure tends to be complicated, and construction of a control device for automatic operation is required, and it is difficult to install it in an existing building. This caused many problems and also took up a large amount of space in the installation location.

Therefore, there is a need for a suspension holding device that has a simplified structure and occupies a relatively small space, which allows the rescue bag to be dropped outside the building by manual operation, the link mechanism is lifted, and the rescue bag is held suspended.

By the way, as such a suspension holding device, a suspension mechanism stored in a mount attached to a building is rotated from the front side to the top about an axis provided on the mount, and then it is brought down outside the building. One possibility is to drop a rescue bag and hang it up.

However, in such a system, when a large number of evacuees rush in during an emergency, the space becomes narrow and it becomes impossible to secure enough space to rotate the suspension mechanism and drop and suspend the rescue bag, making it difficult to evacuate. become unable.

Also, lifting the suspension mechanism requires a large amount of force as the mechanism is quite heavy.

This idea was made in view of the above-mentioned circumstances.The link mechanism connected to the rescue bag is lifted vertically to suspend the rescue bag, and when the link mechanism is lifted, it is pushed in this direction. By providing a lifting mechanism that applies a lifting force, the link mechanism can be easily lifted vertically without requiring a large space even when a large number of evacuees rush in, and in the event of an emergency such as a fire, The object of the present invention is to provide a suspension holding device for a rescue bag that can be easily evacuated outside a building.

Examples of this invention will be described below with reference to the drawings.

1 to 4 show an embodiment of this invention.

In these drawings, 1 is a vertically suspended rescue bag, 2 is a link mechanism that attaches the upper end of this rescue bag 1 and holds it suspended, and 3 is fixed to the floor of a desired floor including the roof of the building, and is made of shaped steel, etc. This mounting base 3 supports the link mechanism 2, and normally stores the rescue bag 1 and the folded link mechanism 2, and covers them with a cover (not shown).

Reference numeral 4 denotes a lifting mechanism for pushing up the link mechanism 2. In the lifting mechanism 4, the lower ends of a pair of upper arms 6a and the upper ends of a pair of intermediate arms 7 are rotatably connected by pins 5a. The intermediate arms 7 are rotatably connected to each other in an X-shape at their center portions by pins 8b, and the lower end portions of the intermediate arms 7 and the pair of lower arms 6. b
are rotatably connected to the upper end portions of each by pins 5b,
The upper end of the upper arm 6a is rotatably connected to the lower end center of the horizontal rod 9b of the support frame 9 of the link mechanism 2 by a pin 8a, and the lower end of the lower arm 6b is connected to the mounting base 3. It is rotatably connected to the eye plate 10b fixed to the eye plate 10b by a pin 8C, and includes a stretchable structure 11 (hereinafter referred to as "stretchable structure") configured in a pantograph shape with two diamond-shaped parts stacked vertically. There is.

Both ends of a horizontal tension spring 12 are connected between the pins 5b on both sides that connect the intermediate arm 7 and the lower arm 6b.

Reference numeral 13 denotes a pair of guides that support the lower ends of the columns 9a of the column frame 9 and guide them to move up and down in the vertical direction.

In the rescue bag suspension holding device configured as described above, during normal operation, that is, when the rescue bag 1 and the link mechanism 2 to which the upper end of the rescue bag 1 is connected are stored, the lifting mechanism 4 is moved as shown in FIG. The extensible structure 11 is in a flat, contracted state.

When the cover (not shown) is removed, the rescue bag 1 is dropped outside the building, and the support frame 9 is lifted and set, the weight of the rescue bag 1 causes the link mechanism 2 to rotate in the direction of arrow A in FIG. The rescue bag 1 is extended outward and is held suspended by the link mechanism 2 as shown in FIG.

During this operation process, the lifting mechanism 4 interposed between the support frame 9 and the mounting base 3 causes the telescopic structure 11 to be extended as shown by arrow B in FIG. 2 due to the tensile force of the tension spring 12. , pushes up the support frame 9, helps the force of a person to lift the support frame 9, and makes it possible to easily raise the support frame 9.

In addition, in the above-mentioned embodiment, the tension spring 12 was provided only in the lower diamond-shaped part of the telescopic structure 11 to urge the telescopic structure 11 in the direction of extension, but as shown in FIG.
If a tension spring 14 is provided horizontally between the pins 5a on both sides connecting the upper arm 6a and the intermediate arm 7, and the upper diamond-shaped part of the telescopic structure 11 is also biased in the direction of extension, the biasing force will be increased. , the support frame 9 can be raised more easily.

Further, as shown in FIG. 6, the intermediate arm 7 of the embodiment shown in FIGS. A telescopic structure 11 consisting of individual diamond-shaped parts is constructed, and a tension spring 1 is inserted between the pins 5 on both sides.
2, or as shown in FIG. 7, a pair of upper arms 6a are rotatably connected to each other at their central portions to form an X-shape. 6
The upper end of the lower arm 6b is pivoted to the horizontal rod 9b of the support frame 9, and the lower end of the lower arm 6b is pivoted to the mounting base 3 at two locations.
a and the lower arm 6b are rotatably connected to each other at their opposing ends to form a telescopic structure 11, and a tension spring 12 is installed between the pins 5 on both sides connecting the upper arm 6a and the lower arm 6b. Even with the lifting mechanism 4 equipped with this, substantially the same effects as those of the embodiments shown in FIGS. 2 to 4 can be obtained.

Furthermore, as shown in FIG. 8, pins 15 provided on each of the pair of lower arms 6b of the telescopic structure 11 having the same configuration as that shown in FIG. is board 1
Even if the tension springs 12 and 14 are connected between the 6 and 6 to urge the elastic structure 11 in the direction of extension, the
Substantially the same effect as the embodiment shown in the figure can be obtained.

As explained above, this invention uses a spring to bias the extensible structure of the lifting mechanism, which is interposed between the support frame of the link mechanism that suspends the rescue bag and the mounting base, in the direction of extension. Since the frame is pushed up, the link mechanism can be easily lifted vertically even in a small space, and when lifting, the lifting mechanism can provide an auxiliary lifting force. The rescue bag can be easily suspended and held by raising the mechanism, and has the effect of providing a rescue bag suspension holding device that facilitates evacuation in an emergency.
